| 摘 要： | 本文分析了迄今为止学术界对如何提高作物产量潜力方面的研究，重点指出作物的种植效益已经开始下降，进一步提高作物的产量和产量潜力已经变得越来越困难，作物的产量潜力是有极限的；提出了作物产量的“系统潜力“理念，将提高作物产量潜力的途径归纳为育种手段、栽培措施、优化投入、控制逆境和改善环境5个方面。

| Abstract: | In this paper,two new kinds of crop yield potentials the inherent and the extrinsic are put forwarded.It is analyzed how to enhance crop's yield potential in the paper,into which the research has already been done a lot up to new.The paper focuses on that cropping benefit has begun to decline,it becomes more and more difficult to enhance crop's yield further, and crop's yield potential is limited. In addition, the idea systematic potential of crop yield is suggested as well.The approaches how to enhance crop's yield and its potential is generalized as breeding techniques,cultivation measures, input optimization,stress control and environmental improvement. |
